Abstract

MÉTODO PARA ESTIMAR UMA IMAGEM QUE MAPEIA UM PROCESSO BIOLÓGICO, PROCESSADOR DE SINAL, DISPOSITIVO, SISTEMA, CÓDIGO DE PROGRAMA EXECUTÁVEL POR COMPUTADOR, E, MEIO DE ARMAZENAGEM LEGÍVEL POR COMPUTADOR Um método, processador de sinal, dispositivo e sistema para estimar uma imagem 47 paramétrica ou funcional, mapeando um processo biológico com base em uma seqüência limitada ou incompleta de imagens 40 de processo biológico gravadas como uma função do tempo, por exemplo, por um scanner PET ou SPECT após a injeção de um radio contraste. Um ou mais parâmetros cinéticos 43 são primeiramente extraídos aplicando um modelo farmacocinético 42 (modelo compartimental da cinética fundamental de contraste) à seqüência de imagens 40 do processo biológico. Dados adicionais 41 são usados no modelo, compreendendo pelo menos uma faixa de parâmetro cinético (por exemplo, a partir da literatura), e opcionalmente uma função de entrada ou uma função de depuração plasmática do sangue. A seguir, um algoritmo iterativo 44 é aplicado para chegar a um seqüência modificada de imagens 45, por exemplo, inserido uma imagem estimada na seqüência incompleta de imagens, utilizando um ou mais parâmetros cinéticos 43. Após um critério de parada ter sido satisfeito, a imagem resultante 47 é finalmente estimada 46 a partir da seqüência de imagens 45 modificada. O método pode ser usado, por exemplo, para estimar uma imagem k3 de parâmetro de hipoxia no caso de um conjunto de dados FMISO, onde somente imagens tardias estão disponíveis. O método pode ser implementado como parte de software de scanner existente, PET, SPECT, CT, MR ou Ultrassom, e uma vez que somente uma quantidade limitada de imagens tardias pós injeção são necessárias para prover um resultado confiável, o método auxilia a aumentar o conforto do paciente e produtividade operacional clínica.
